1(a) A D.C. circuit has been setup as shown in Figure 1(a). Apply the Kirchhoff's Voltage Law to resolve questions below. (i) Copy the below circuit to your answer book, insert the voltage arrows for (5 marks) each circuit component, and label loops in your circuit. (ii) Write the two loop equations for WXUP, and XYZU in terms of 11 and 12. (2 marks) (iii) Determine the values of I, and 12. (4 marks) (iv) Calculate the power dissipation for the 32 resistor. (1 mark) (v) An analogue ammeter is connected in series with the resistor Rs for (7 marks) measuring the current 12. However, measured value is not matched with the calculation results. Explain the situation and propose another method to obtain a more accurate result. w 11 X 12 E3 Y RI W 10022 384V (11-12) Ει 256V R3 320 WW RS 12492 E2 160V R2 R4 W 26092 Р 2892 U Z Figure 1(a) (b) A resistor network is built as shown in Figure 1(b), With the application of 6 marks) Kirchhoff's Current Law, determine the unknown currents I1, 12, 13, and 14. 11 NI 2A W W 13 WW 0.5A 4A N2 N4 1.5A NS 3A W N3 0.5A my 12 w N6 Figure 1(b)
